BIO 1150: Human Anatomy & Physiology I
1. What is anatomy?
A. The study of body functions
B. The study of body structures
C. The study of diseases only
D. The study of medications
ANSWER : B. The study of body structures.
Explanation: Anatomy examines the structures of the body, including
organs, tissues, bones, and their relationships to one another.
,2. What is physiology?
A. The study of body functions
B. The study of body shapes only
C. The study of microorganisms only
D. The study of fossils
ANSWER : A. The study of body functions.
Explanation: Physiology explains how body parts work, such as how the
heart pumps blood and how muscles contract.
3. Which level of organization is the simplest?
A. Organ
B. Tissue
C. Chemical
D. Organ system
ANSWER : C. Chemical.
Explanation: Chemical organization includes atoms and molecules, which
form the building blocks of cells and larger body structures.
4. Which sequence correctly represents the levels of organization from
simplest to most complex?
A. Organ, tissue, cell, chemical, organism
B. Chemical, cellular, tissue, organ, organ system, organism
,C. Tissue, chemical, organ, cellular, organism
D. Cell, organ system, tissue, chemical, organism
ANSWER : B. Chemical, cellular, tissue, organ, organ system, organism.
Explanation: Atoms and molecules form cells; cells form tissues; tissues
form organs; organs work together in organ systems.
5. What is homeostasis?
A. The complete absence of change
B. The maintenance of a relatively stable internal environment
C. The breakdown of all body tissues
D. The production of new cells only
ANSWER : B. The maintenance of a relatively stable internal environment.
Explanation: Homeostasis keeps variables such as temperature, blood
glucose, and pH within suitable ranges despite changing conditions.
6. Which body system provides rapid communication using electrical
signals?
A. Digestive system
B. Nervous system
C. Skeletal system
D. Integumentary system
ANSWER : B. Nervous system.
, Explanation: The nervous system uses electrical impulses and chemical
neurotransmitters to coordinate rapid responses.
7. Which body system produces hormones that regulate body functions?
A. Endocrine system
B. Skeletal system
C. Integumentary system
D. Respiratory system
ANSWER : A. Endocrine system.
Explanation: Endocrine glands release hormones into the bloodstream to
regulate growth, metabolism, reproduction, and other processes.
8. What is the standard anatomical position?
A. Standing upright, facing forward, arms at the sides, palms forward
B. Sitting with palms facing backward
C. Lying flat with arms crossed
D. Standing with the head turned sideways
ANSWER : A. Standing upright, facing forward, arms at the sides, palms
forward.
Explanation: The standard anatomical position provides a consistent
reference for describing body structures and directions.
